Claims. `(Cl. 108-10) UNITED STATES. PATENT ori-ica This invention relates to roofing ticularly glass rooting. l

Hitherto, to anchor the glass tiles in glass roofing metal ledges have beenused which are! 5 placed over the interstices between adjoining tiles and secured in position by suitable metal members which project from the'roof surface and are attached to the rafters. Such projecting members are objectionable, since due to atmospheric conditions, they rapidly deteriorate,

thereby rendering the structure weak and insecure.

The object of this invention is to obviate these objections and eliminate projecting parts exposed to atmospheric-influence.

To accomplish this object, my invention corn-- and j parprises a device including a glassledge adapted to extend over the interstices between adjoining tiles and formed with a boss extending down:- wardly through theiintersticesand means for engaging said boss and anchoring said ledge to the rafters of the roof. l With these and otherobjects in view, this invention consists in the novel construction, com- 5 bination and arrangement oi' parts aswill be hereinafter more fully described and deiined in the appended claims. v In the accompanying drawing ,which'constitutes part of thespeciiication, in which similar referencev characters denote correspondmgparts Figs. 1,.l 2.and 3 are three `differentmociiilc'aationis of the device tormingthe 1 subject `oi thisinvention"andfFig. ;3" is a ver` vtical -section -of af modified llei'lgejto'fb-e used with the modiiled :'coustruxtioiif1offthe"f-"tiles- Shoilml l f' edge isfo'rmedwithapair of beads 3'? between j f fRefe ng shown) v areI in 'alignment-,f with theinner' edgesjofv said 5 tiles.

From the free ends of each of said loops B is suspended a hook-shaped member 9 carrying a nut Ill which Y serves for the attachment of a ilexible plate H of steel or the like whose lateral edges are 10 bent over and engage the lower ends-of the angle irons li. The free edges of each of said j plates il are iorm'ed with suitable projections l2 to engage a drain I3 for condensing water. This drain i3 is formed of a flexible sheet of l5 metal provided with lateral projections I3' whereby the same may be easily snappedto or removed from its supporting parts. By tightening the nut i0 the loop 8 is tensioned and the v ledge 4 pressed against the tiles H, thereby 20 compressing the elastic packing pads 'i and pro-i` ducing perfectly water-tight seals both on top and bottom of said tiles. i

In the modification shown in Fig. 2, in lieu` of the pads 1, the opposite edges of the adjacent g5 tiles 3'-3 are formed with upwardly extending beads b-Sb and the ledge 4'k at each side `of the interstice is formed with a pair oi' down-l on the tile 'Ihe projections 3b of the tiles'serve to limit or prevent lateral displacementfoi the f ledge 4. g y f j According to the modiications shown in Fig. 3, inlieu of the'pads 'lb eachtile I near'its inner l which a suitable packing strip'lb bearing, on` Vthe-tile is mounted. In lieu of the ledge 4 shown yinn-Zitig.` 3, a ledge 42 may be provided whichat gin Fig.: 3*. said beads 4b being adapted in coop- 4eration with the beads 3c ,to limit or prevent lateral displacement of the ledge 4.

yIt is understood that variouschanges maybe 45 made in my device without ,departing from the not wishv to limit myself-to the details described l, and shown.V i v What! 'claim is: ,j so 1. In aroof comprising tiles of glass' or the j like, a of spaced supporting members for said tiles, ajledge overlapping the edges of ad-l `joining tiles and covering the interstice between them, said ledge being` formed` with a boss pros jecting downwardly through the interstice between said adjoining tiles, flexible means embracing said supporting members and tension means between said boss and said Iflexible means 5 for anchoring said ledge in position.

2. In a roof according to claim 1 in which said supporting members consist of a pair of angle bars arranged in spaced relationship corresponding to the width oi' the interstice between ad- 10 joining tiles, and said anchoring means include a flexible plate embracing said supporting mem.- bers.

l 3.Inarooi' accordingto claim 1 in which said ledge is made oi' glass and is formed centrally with a downwardly projecting transversely perforated boss to extend through the interstice between adjoining tiles and between said supporting members.

4. In a roof according to claim 1 in which said boss is anchored to said means embracing said supporting members by loops suspended therefrom and tension members suspended from said loops and clamped to said bracing means.

5. In a roof according to claim 1 in which a drain for condensing water is removably suspended from said bracing means.
